+Fully re-mappable GCN controller to Luma InputRedirect.
+Also supports remappable keyboard inputs.
 
-Technically supports any DInput device (i.e. Windows joystick), or any device that PyGame natively supports, but is currently mapped for a Gamecube Controller via a USB adapter.
+Technically supports any DInput device (i.e. Windows joystick), or any device that PyGame supports (i.e. XBox 360 Controller), but is currently mapped for a Gamecube Controller via a USB adapter.
 
 To remap controls, just edit the buttonMappings array or KBDButtons class in gamepad.py (or two.py if using multiple systems). 
 
-The buttonMappings array is just every button on your controller in order from 0, so if you want button 0 on your controller to be button A on the 3DS, put `HIDButtons.A` first in the list. 
+The buttonMappings array is a list of every button on your controller in order from 0 mapped to a 3DS button, so if you want button 0 on your controller to be button A on the 3DS, put `HIDButtons.A` first in the list. 
 Likewise, if you want button 3 to be A, put `HIDButtons.A` as the 4th item in the list. 
 If you want a high-numbered button (like the XBox 360 Guide button, 15 on some OSes) to be bound to a 3DS button, just add empty list entries (zero) in between the last button map and the one you want.
